摘要

PPROBLEM TO BE SOLVED: To solve such a problem that, in order to obtain a wide band amplifier circuit that holds a flat gain over a wide band in a high frequency region which is close to the maximum oscillation frequency fSBmax/SBof a transistor, with no margin in performance, such circuit configuration is required as is simple as much as possible and uses only a no-loss element, since a resistive element cannot be used in a matching circuit because of large loss. PSOLUTION: In an n-stage amplifier circuit, transistors 11, 12... 1n whose size increases stepwise, from input toward output, are connected in cascade arrangement. Matching circuits 21, 22... 2n are designed to have high-pass characteristic, and its cut-off frequencies (lower cut-off frequency) fSB1/SB, fSB2/SB... fSBn/SBbecome lower stepwise from input toward output.

要解决的问题：解决这样的问题，以便获得在接近最大振荡频率f 的高频区域中在宽带上保持平坦增益的宽带放大器电路晶体管的最大，在性能上没有裕度，这种电路配置需要尽可能简单，并且仅使用无损耗元件，因为电阻元件由于尺寸大而不能用于匹配电路中失利。

解决方案：在n级放大器电路中，晶体管11、12 ... 1n的大小从输入到输出逐步增大，以级联方式连接。匹配电路21、22 ... 2n被设计为具有高通特性，并且其截止频率（更低的截止频率）f 1 ，f 2 ... f n 从输入到输出逐渐降低。
